As someone who has worked on quite a few of both types of engines all I can say is the low RPM types seem to run just as long, or longer than the hig RPM engines. As far as crank journal wear goes, as long as you use a good quality oil, and maintain it properly, wear should be negligable on either one, regardless of how long it has been run. Heck, I've seen some of the old engines ( Ie- 4 and 6 cylinder Murpys) that had been in service for 20 years and are still running great, and some that were worn to the point that you could literally move the crank up and down with a pry bar. Even with the worn crank the engine was still running, but the guy had switched to a mizture of engine oil and 90w gear oil to keep the pressure up until we could find him a replacement engine. By the same token I've seen high speed engines in daily service for 12 plus years with absolutely no crank, liner, or rod bearign wear, and some with half that amount of use that were worn completely out. In all cases proper maintenance, more than anything else, was the root cause of the wear, or lack thereof. In other words, take care of your engine and it will take care of you, don't, and it will cost you way more in the end than using quality lubricants, and filters, ever would.
